Title: Process for processing sticky plastic compositions in injection moulding machines and device for carrying out the process
Inventor: SAUERBRUCH ERNST
IPC: B29C45/72
Filed: 1987-07-24
Abstract: The charging device of an injection moulding machine for polyester processing has a charging cylinder and a stuffing ram with which the polyester material is forced into the plastication unit of the injection moulding machine. In the ram head of the stuffing ram, cooling channels are arranged through which a cooling liquid flows. As a result of the supercooling, a condensate layer forms on the ram head which prevents the sticking of the polyester material to the ram head. In this manner, other machine parts of the injection moulding machine which come into contact with the polyester material can also be cooled.

Title: Process for producing a packing sleeve of polytetrafluoroethylene
Inventor: DEURING HANS DIPL ING
IPC: F16J15/328
Filed: 1987-09-23
Abstract: In a process for producing a packing sleeve of polytetrafluoroethylene or a related polymer for use in lip-type sealing rings, in which the packing sleeve is gripped in the adhesion-part section between the housing ring and the clamping ring, the packing sleeve is bent over at the inner circumference towards the packing lip bearing against the shaft or rod and the packing sleeve has on the outer circumference an additional axial leg which, provided with a packing profile on the end, bears against the receptacle groove of the housing, the deformation of the individual packing sleeve sections and the embossing of the packing profile and of the running-surface return twist are carried out from the flat packing disc punctured by a tube in separate process steps, so that rebound forces of the deformed disc occur essentially on the inner and outer circumference and can be utilised for pressing radially against the static and dynamic packing surfaces, whereas the adhesion-part section, in particular, remains free of deformation stresses and thus free of uncontrollable and undesired rebound forces. <IMAGE>

Patent DE-3733787-A1 (DE)
Inventor: CLARE MANAMOHAN
IPC: F15D1/00
Filed: 1987-10-06
Abstract: A muffler for reducing noise generated by turbulent water flowing from a valve or other fitting has a housing portion (12) with an inlet (16) which leads to a pair of circuitous flow paths (20, 22), one of which is adapted to carry substantially more water than the other. The flow paths meet at a common discharge area (30) from which the water flows through a plurality of small diameter holes (34) in a cover portion (14) to an outlet defined by the cover portion. The flow of turbulent water is rendered more laminar by the muffler and consequently noise generated due to the turbulent flow itself or due to vibrations induced by the turbulent flow is reduced. <IMAGE>

Title: Thread storage and delivery apparatus
Inventor: SHAW HENRY
IPC: B65H51/22
Filed: 1987-10-09
Abstract: In the event of a thread break, the thread (Y) has to be threaded in again. This is carried out either by hand, thus increasing the standstill times and the labour in an impractical way, or, in a known apparatus, by means of a mechanical threading-in apparatus assisted by flow nozzles. This takes up a large amount of space, is complicated to control and is multi-part. The new thread storage and delivery apparatus is to allow a rapid automatic threading-in. So that an automatic threading-in of the thread (Y) can be carried out with a small amount of space required, in a constructionally simple way and without moved parts, the threading-in apparatus possesses, between the region of the outlet (11) of the thread-feed member (9) and the guide orifice (22), a compressed-air transport system (E) having stationary directional blowing nozzles (33, 33', 33'', 33''', 35, 37, 37', 58) which, when activated, deliver the thread (Y) to the guide orifice (22) by means of an air flow. The directional blowing nozzles form a flow which runs as far as the guide orifice (22) and which brings the thread (Y) into the guide orifice (22) without movable elements and without control members. The thread storage and delivery apparatus is suitable particularly for fully automatic textile machines on account of the simple automatic threading-in. <IMAGE>

Patent DE-3740725-A1 (DE)
Title: Motor-driven air movement apparatus for continuous operation at high speed
Inventor: SAVAGE JACK W
IPC: H02K29/08
Filed: 1987-12-01
Abstract: A motor-driven air movement apparatus for operation at high speed and switched on continuously has a DC permanent-magnet motor with a stator and a rotor, a winding core (20) being provided with an even number of teeth (113) of identical shape and at a uniform spacing, while the other component has an even number of identically formed permanent-magnet poles. An inclined angle against the axial direction is provided in one of the two components, the maximum achievable incline angle being less than one tooth pitch as a result of the short axial length of the core. A groove (116) is provided along the centre line of each tooth of the core, is parallel to the winding slots (115) between the teeth, is flatter than them and contains no winding. The groove results in the tooth being magnetically divided into two halves and thus reduces the effective tooth length, as a result of which the magnetically induced pulsation of the angular speed of the rotor and the audible noise resulting from it are at the same time reduced, and the system efficiency of the combination of the motor apparatus and air movement apparatus in continuous switched-on operation at high speed is increased. <IMAGE>

Patent DE-3824347-A1 (DE)
Title: Electrode for dielectrically heating thermoplastics
Inventor: DREES MARIO DIPL ING
IPC: H05B6/54
Filed: 1988-07-19
Abstract: The invention relates to an electrode for dielectrically heating thermoplastics. The electrode material or the conducting layer has in this case, compared to normal metal conductors, a relatively high resistance. As a result, the electrode heats itself. In this way, the temperature gradient between workpiece and electrode is reduced and in consequence the heat flow (heat dissipation) in this direction. Welding or embossing thus improves in quality and in particular embossing is possible without additional insulating material.

Title: Motor-adjustable head restraint
Inventor: BAUER HEINZ
IPC: B60N2/48
Filed: 1988-08-23
Abstract: The motor-adjustable head restraint for the back rest of a vehicle seat is provided with a driving unit, to which a motor (36) and a reduction gear belong, and a support cushion which can be adjusted between a storage position, in which it is located behind the back rest, and a support region, as well as within this support region, about a support hoop (22) which is mounted pivotably and is connected to the driving unit by the gear. In order to configure the angular speed of the adjusting movement within the support region such that it is clearly lower than for the swinging-up from the storage position into the support region, it is proposed that the gear have a reduction ratio which is dependent on the swivelling angle of the head restraint, the reduction ratio being clearly larger for an adjustment within the support region, in particular being at least twice as large as the reduction ratio for an adjustment between the storage position and support region. <IMAGE>
